In general, in the field of materials or condensed matter, the preparation of polymer brushes on solid surfaces is of great interest for surface modification and composite material preparation [4-6]. A number of model surface grafting techniques have been used on planar surfaces and particles and have been the subject of previous reviews. While a munber of polymer brush preparation methods have been reported using physisorption or chemisorption or so-called grafting onto methods, the emphasis of this review is on surface-initiated polymerization (SIP) methods or grafting from methods.

Single crystal cBN is not of industrial importance for cutting applications as it offers few benefits over monocrystalline diamond and is intrinsically more difficult to synthesize. As such, all industrial cBN tools are composite materials prepared using powder metallurgical techniques, but sintered under similar conditions to those used for the synthesis of diamond and cBN from their softer allotropes (graphite in the case of diamond).

Additional specimens were prepared by melting and kneading sodium-type montmorillonite (unorganized type) and nylon 6 using a twin screw extruder at 250 °C for the purpose of comparing them with the specimens prepared as described above. This method of preparing specimens is commonly used when compounding particulate fillers with polymers. The composite material prepared in this way was called NCC (Nylon 6-Clay Composite), and the NCC was compared with the NCH.

In a parallel study, a biocompatible composite made of sulphonated PSU and HAp was prepared and characterized. The incorporation of HAp was achieved by spontaneous precipitation of HAp at controlled conditions of pH and temperature. The time of the precipitation process was used to regulate the content of inorganic component in the composite. The composite material prepared in this experiment contained 9 wt% of HAp and 91 wt% of polymer. Analysis of the kinetic results of the crystallization process showed that the growth of HAp on the film-shaped composite material followed a polynuclear (nuclei above nuclei) crystal growth mechanism [103],...

Composite materials, prepared with this aluminosilicate network binder and quartz sand, demonstrate a remarkable increase of the chemical durability against water and 70 wt.% H2SO4 (both at 100 °C, 6 h) with rising addition of Al4(P40i2)j up to 30 wt.%. With respect to the useful chemical durability and the compressive strength of about 22 N/mm these composite materials have a large application potential in the fields of waste-water pipes and collection units.
